Ok I see, please note that changes made to the theme directly will be lost during an update. If you have added those changes to a custom child theme then all good 
Blockify provides a filter to add custom icon sets from a child theme (or plugin) – https://github.com/blockifywp/theme/blob/main/includes/utility/icon.php#L56
The reason the icons use the webkit mask is to allow gradient colors to work, without a mask they can’t use gradients. You could try adding some padding to the block, or setting a fixed height.
Is it possible to share the URL so I can take a look for you? It should be possible to share it privately in this support thread.
